What is wireless network service?
A wireless network is a computer network that uses wireless data connections between network nodes. Examples of wireless networks include cell phone networks, wireless local area networks (WLANs), wireless sensor networks, satellite communication networks, and terrestrial microwave networks.
What are the service modes of wireless networks?
Wireless LAN 802.11 Service Sets
- IBSS.
- Infrastructure Mode. Basic Service Set (BSS) Distribution System (DS) Extended Service Set (ESS) Mesh Basic Service Set (MBSS)
What is QoS in wireless networks?
Quality of service (QoS) refers to any technology that manages data traffic to reduce packet loss, latency and jitter on a network. QoS controls and manages network resources by setting priorities for specific types of data on the network.
What is WLAN AutoConfig?
Once enabled, the WLAN AutoConfig service dynamically selects which wireless network the computer automatically connects to, and configures the necessary settings on the wireless network adapter. This includes automatically selecting and connecting to a more preferred wireless network when one becomes available.
What is Bssid and SSID?
BSSID is the MAC address of the AP’s radio for that service set. SSID is the service set identifier or network name for the basic service set(BSS). ESSID is the same as the SSID but is used across multiple access points as part of the same WLAN.
What is basic service area?
A Basic Service Area (BSA) is the physical area of RF coverage provided by an access point in a BSS. The access point is the master for the cell and controls traffic flow to and from the network. The remote devices do not communicate directly with each other; they communicate only with the access point.
What is latency network?
Network latency, sometimes called lag, is the term used to describe delays in communication over a network. Latency meaning in networking is best thought of as the amount of time it takes for a packet of data to be captured, transmitted, processed through multiple devices, then received at its destination and decoded.
What is jitter in networking?
Jitter is when there is a time delay in the sending of these data packets over your network connection. This is often caused by network congestion, and sometimes route changes. Essentially, the longer data packets take to arrive, the more jitter can negatively impact the video and audio quality.
Why is quality of service important in wireless networks?
Quality of service (QoS) is an important consideration in networking, but it is also a significant challenge. Providing QoS guarantees becomes even more challenging when you add the complexities of wireless and mobile networks. This paper discusses the challenges and solutions involved in providing QoS in wireless data networks.
What does it mean to have wireless internet service?
Wireless broadband internet service generally refers to a package deal that combines both the wireless technology and broadband service, and to which you can subscribe to.
What is Network Time Protocol ( NTP ) used for?
Network Time Protocol (NTP) is a protocol used to synchronize computer clock times in a network. It belongs to and is one of the oldest parts of the TCP/IP protocol suite. The term NTP applies to both the protocol and the client-server programs that run on computers.
What is the theoretical speed of wireless internet?
EDGE transmits data at approximately 236.8 kbit/s, which is below the standard for a broadband connection. However, its theoretical maximum speed is 473.6 kbit/s, so it still considered a wireless broadband technology.
